Thanks Daniel... i did what you requested. Following is a recap of the process, FYI:
1. System running Nouveau driver. All OK. 2. Open terminal, input "sudo apt install nvidia-driver-390". 3. After installation complete, input "systemctl reboot" to reboot. 4. Screen went blank on reboot, cursor blinking at around the top left corner. 5. Pressed Alt Ctrl F2 to bring up tty2, then input "sudo apt-get remove --purge nvidia-*" to remove nvidia driver. 6. After removal complete, input "systemctl reboot" to reboot. 7. Reboot OK. System OK with Nouveau driver. 8. Ran journalctl 5 times to generate the attached 5 files. Here are the 5 journals. Thanks. ** Attachment added: "boot-1.txt" https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390/+bug/1864781/+attachment/5331429/+files/boot-1.txt -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-340 in Ubuntu. https://bugs.launchpad.net/bugs/1864781 Title: System with GeForce GT 520 failed to boot when nvidia-390 was installed Status in linux package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-340 package in Ubuntu: Won't Fix Status in nvidia-graphics-drivers-390 package in Ubuntu: New Bug description: System booted OK with Nouveau driver.
